Scrobble videos watched from other sources

many of these free websites are pulling their video links from online storage websites such as putlocker.is
some of these websites get taken down and come back, or new ones appear. and the videos get taken down, and put back up with a different link.

in order to track and scrobble these, id suggest inferring from the the video name, or video link, as well using their fingerprint software/hashing the video. could be done as the video is loading into temp folder maybe?
